Welcome here. I am new here and last Friday I ordered my Solidoodle 3. I was also looking into the Makerbot Replicator 2, but after reading stuff on the Internet and watching some vids I decided against it. Form what I gathered is their quality has gone way down hill and most Replicator 2s don't work when received and break easily.
Also the price is a big concern. The un-built model is $2100 and a built one is around $2700. I could buy 3-4 Solidoodles for the price of one Makerbot. Also the print area is smaller, it's only 15x6x6, where as the Solidoodle 3 is 8x8x8. They both have the same resolution, in theory 0.1m layers. The makerbot software in easier to use, but has no fine tuning options. Rumor is that they have locked down the system to outside software, but haven't had any proof for or against.
